What is the approximate pH of the equivalence point in the titration pH curve?
Without seeing the curve, we can't answer this.
Which curve was most likely generated from analysis of an enzyme from a human stomach where conditions are strongly acid?
curve 4 curve occurs in small ph have stronger acid
What is the titration curve of phenylalanine?
The titration curve of phenylanaline is around pk value 6.89 which neutral pH. It has a two buffer one in the acidic portion and the neutral one.
Is the pH scale linear?
NO!!! The 'p' in pH is short for 'the negative logarithm to base 10. The 'H' is for the hydrogen ion concentration. pH = -log(10)[H+] Mathemtically inverting [H^+] = 10^(-pH) So pH = 1 is equivalenrt to 10^-1 = 0.1 pH = 2 is equivalent to 10^-2 = 0.01 pH = 3 is equivlaanrt to 10^-3 = 0.001 : pH = 7 is equivalent to 10^-7 = 0.0000001 : pH = 14 is equivapanet to 10^(-14) = 0.00000000000001 So hopefully you can see that is is decreasing in powers of '10'. on an exponential scale. On a graph this will produce a curve, not a straight line.
Is phenolphthalein the indicator used in the titration of Na2CO3 against HCl solution?
Type your answer here... Phenolphthaelin indicator changes its colour at 8.3 pH. But the end point of this reaction is at pH 7. In weak base Strong acid case the curve gives sharp change from 3.2 to 6.0 pH. Hence phenolphthalein indicator will not be advicable.

What is a Stephan curve?
a curve representing the change of plaque pH over a period of time.
Which curve was most likely generated from analysis of an enzyme from a human stomach where conditions are strongly acid?
curve 4 curve occurs in small ph have stronger acid
What are the Causes of right shift of oxygen dissociation curve?
change in pH , temp. carbon dioxide 2,3 BPG shifts the curve
What is stephen's curve?
Stephen curve is a graph plotted on pH level against time. This graph will show that the food intake will reduce pH level in the mouth to a level bad for teeth and then rises again with time.
What are sigmoid and Stephens curve in diet and dentistry?
Stephens curve is a graph plotted on pH level against time . This graph will show that the food intake will reduce pH level in the mouth to a level bad for teeth and then rises again with time.

Can you flash your unlocked blackberry curve pH from ATT to Verizon service?
no you cannot, one is gsm and the other is cdma
What is the bayliss curve?
One method of determining whether the pH and alkalinity are properly adjusted to produce stable, non‑corrosive water is with the Baylis Curve. Plotting the pH and alkalinity of the water on this chart will indicate whether the water is corrosive or not. If the point where the pH and alkalinity cross is below the curve (dark gray area) the water is corro­sive and will attack metal tanks and pipes in the system. If the point is above the curve the water is not corrosive but does have excessive amounts of alkalinity present, which will cause the formation of lime scale in the lines. This scale formation can restrict the flow of water in the line if al­lowed to build up over a long period of time and can be as bad for the system as corrosive water. When the point falls within the dotted lines or on the curve itself, the water is stable and will not cause corrosion problems.
Could you find the average pH level for soil in state of New Mexico?
no. soil pH will vary by region in new mexico. although almost all the soils will be quite alkaline. if you were to run a modal bell curve, most soils would probably fall out around pH of 8.0.
